WPLoadTester 7 ships in two editions. Free is permanent and runs on the machine you install it on, with no artificial virtual-user cap. Pro adds distributed load generation from your own AWS or Azure account, AI-written bottleneck reports, the full server-monitoring metric set with AWS CloudWatch and Dynatrace integration, and business-hours support. Below is every difference, in the same order the in-app signup screen presents them.
| Feature | Free Account | Pro License |
|---|---|---|
| Load Generation | Local, no VU limit | Generated from your AWS or Azure account |
| AI Test Configuration | ✓ † | ✓ † |
| AI Bottleneck Reports | Not included | ✓ |
| Test Configuration Expert System | ✓ | ✓ |
| MCP Server | ✓ † | ✓ † |
| Server Monitoring | Basic (CPU, memory, disk) | Full metrics + AWS CloudWatch + Dynatrace |
| Cloud Results Sharing | ✓ | ✓ |
| Support | Community | Business hours |
† Bring your own OpenAI, Anthropic, Azure OpenAI, or AWS Bedrock key. You pay your AI provider directly. WPLoadTester adds no markup on AI tokens.
The Free edition generates load from the machine you install WPLoadTester on. CPU and upstream bandwidth are the only caps. Pro launches load from your own AWS or Azure account, distributed across regions, scaling from a handful of users to a million. The cost of cloud compute time goes to AWS or Azure on your own bill, not through WPLoadTester. See cloud load testing
The Analytics Dashboard itself ships with both editions. Open a finished test and the six tabs (Overview, Analysis, Pages, Servers, Errors, Report) render the same way. The difference is the Report tab. In Free, the Report tab shows the dashboard's deterministic analytics: capacity numbers, page rankings, server correlations. In Pro, the AI reads all of that and writes the analysis in plain English, with named bottleneck sources, affected pages, and the user level at which response time goes vertical. See the Analytics Dashboard
Free includes the three foundational metric groups: CPU, memory, and disk. Pro adds the remaining metric groups (network, TCP, processes, page faults, swap, and more) plus integration with AWS CloudWatch and Dynatrace, so server-side observability you already pay for shows up alongside the load-test data instead of in a separate tab. See Server Monitoring
Free relies on the community forum and the documentation. Pro adds direct business-hours support from the team, scoped to your license. If your test is on a deadline and you need a human on it, that is the Pro tier.
Every AI-driven feature (AI Test Configuration in both tiers, the MCP server in both tiers, and the Pro-only AI Bottleneck Report) uses your own API key. Anthropic, OpenAI, Azure OpenAI, or AWS Bedrock. You pay the AI provider directly. WPLoadTester is not in the request path, does not store your prompts, and does not charge a margin on tokens. The Pro license unlocks the AI Bottleneck Report feature, not AI pricing. See Bring Your Own AI
